Bug 211823

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
When I try to change the wallpaper and go to the "browse" button, nothing happens and plasma freezes (including cashew, pannel, desktop settings, etc).  After a while, crashes and bug report appears.  
Also have problems with the quick access plasmoid, doesn't show anything at all no matter what folder to show I choose.  I mention it just in case it could be related.

 -- Backtrace:
Application: Área de trabajo de Plasma (kdeinit4), signal: Segmentation fault
